So, for my robotics team I am allowed to use vuforia to detect "VuMarks". This year they just updated the sdk for my programming tools to allow for an external webcam instead of using the camera on the android phone. So, I tested the code for an external webcam and I get an error saying that my license key does not support external camera usage.I checked my License key and there is no option for external webcams. Can some please help me. Thanks

this is the link to the sdk i am using with android studio: https://github.com/ftctechnh/ftc_app
